Complete metal rotor head ensures maximum strength and durability. Extra large in design for high head speed aggressive 3D flying style, designed for today with tomorrows capability. Extra large ball links and push rod allowing the rotor head to pivot for a direct and smooth feel at all rotor head speeds. 12mm main shaft is leading the class in today’s 600 sized helicopters. Integrated pivot ball and internal guides ensures the rotor head motion is in a pivot motion only. Providing increased pitch and cyclic response and stability.

Front and rear gyro mount standard on all models. Ensuring your gyro or remote gyro sensors is located in an area of low vibration.

Extra large polymer impregnated metal plastics gears have been used extensively throughout. Full metal construction increases strength and provides consistent gear mesh for a smooth gear train. Dual radial bearings and a single thrust bearing are installed in each rotor grip for maximum precision and performance. A hard anodized aluminium pitch slider with dual bearing is also included for weight reduction and durability. Dual ball bearings are moulded directly into the pitch links for increased precision and simplicity.

Large diameter boom supports with supporting M4 bolts for superior rigidity. Eliminating boom flex providing a direct tail rotor feel with precise start and stop characteristics during rotation. Ball raced tail bell crank along with carbon fibre push rod providing a smooth flex free operation. The tail servo is placed in front of the engine in a position free from nitro oil while optimizing the centre of gravity of the nitro version.

Eliminating servo movement is critical with flybarless models. A key TSA feature is our innovating servo brace which eliminates all servo output shaft bending stress and flex. This ensures your gyro input is going directly to the rotor head and not in unwanted servo movement. Our servo support also ensures the greatest chance your servos are safe in the event of a crash.

Servo performance is key to the performance of your model and TSA has revolutionised servo layout with its Infusion series. All servos are high in the frame ensuring the centre of mass is as close as possible to the rotor head for increased performance. Direct push/pull elevator servo layout with carbon fibre linkage rods provides a highly precise system.

Included in all kits is our fully adjustable boom support brace. High lateral loads are transmitted from the tail rotor to the boom supports. This load then results in bending force on the boom and mainly the boom supports. Our brace ensures the bending stress is minimized by locking the 2 supports together forming a truss style arrangement. Tail stiffness is critical to the performance of your tail gyro and this is one key area many overlook.

TSA has taken the thinking out of wiring. This area is normally over looked by all and dreaded by most builders. This thankfully is a thing of the past for all you TSA flyers. Included in all kits are rubber moulded grommets protecting your servo wires from rubbing on carbon fibre. This rubbing effect and flapping wires is then eliminated by a multiple selection of wire clamps. Included are single and double servo wire and single servo wire with circular remote gyro wire clamps. We have covered all possible installations, just clip in and enjoy.

Class leaders by design TSA has innovated the anti rotation swashplate feature into our direct 8 bearing elevator assembly. Keeping your swashplate rigid ensure the phasing is maintained at 120 degree. This ensures the pilot input is sent directly to the rotor head.

Frame stiffness is critical to a helicopter as unwanted movement can be transmitted to the gyro system controlling both the tail rotor and rotor head. TSA has integrated X braces with centralised location points providing a 6 point location on each brace. Our wide frame design along with X brace technology provides and extremely rigid helicopter which is fast to build and very resistant to high impact crash damage normally seen by most other models.
An extremely rigid wide frame design with integrated X brace frame stiffeners ensures a low vibration and extremely strong flying model. Polymer impregnated metal plastics used for increased stiffness and weight saving.

Large 650ml tank with moulded rubber dampers to minimise vibration and fuel foaming. TSA Patent Pending fuel pickup system “Fuel Addict” shrouded foam intank pick is also included on all nitro and gas models. Get every last drop from your tank TSA has the solution.
